about the method of practicing

been seeing some videos about how to practice effectively and build correct muscle memory. at the moment i’m doing quite well about fixing the little issues i’ve had during my daily practice bar by bar but the problem is i tend to repeat the phase after all that in the same day and tried to run the scale/arpeggio smoothly for 2-3 times otherwise i feel like i’m carrying something problematic to the next day ( probably unfixed issue or wrong muscle memory?) i feel it’s getting me tired and run counter to what effectiveness means, as i might do few things correctly in the first run and rest not so good but next time i managed them well but some other problems occurs, in the end in order to run it perfectly and smoothly for 2 times i spent a lot of time repeating. i think i did something wrong no?
